| 摘 要： | 现有的许多三方口令认证密钥交换(3PAKE)协议都被发现是不安全的。该文基于通用可组合(UC)模型，定义了3PAKE理想函数。在两方口令认证密钥交换理想函数辅助的混合模型下，构造了一个实现3PAKE理想函数的3PAKE协议。新的协议由中间密钥生成、消息认证传输和会话密钥生成3个阶段构成。该协议是UC安全的，并且结构简单。 |

| Abstract: | Many existing three Party Password-Authenticated Key Exchange (3PAKE) protocols are found insecure.An ideal functionality of 3PAKE is defined in the universal composability model,and a 3PAKE protocol is constructed to realize the 3PAKE ideal functionality in the hybrid model which aided by two party password-authenticated key exchange ideal functionality.The new protocol comprises of three phases: intermediate key generation,message authentication transmission and session key generation.The protocol is UC-s... |
